摘要:

傳統金屬基復合材料在強度和彈性模量提高的同時，塑韌性急劇下降，因此很大程度上限制了它的應用范圍。為了滿足高技術領域的需求，改善復合材料的塑韌性，利用多項增強體同時增強金屬基復合材料的“混雜效應”，在不同尺度、不同層次上進行結構設計和優化，發揮各種增強相的優勢�；祀s增強體之間的相互作用、混雜效應等使得復合材料具備更低的熱膨脹系數、更高的耐磨性和更優越的力學性能等，同時還降低原料的成本。這都使得它成為航空、航天和國防尖端技術領域最富有研究潛力的戰略性材料，并帶動了整個工業技術的進步。本文介紹了混雜增強金屬基復合材料結構種類及其研究進展，綜述了各種構型設計的基本原理及其優缺點；展望了混雜增強金屬基復合材料構型及功能化的發展方向及工程化需要解決的關鍵問題。

Abstract:

When improving the strength and elastic modulus of traditional metal matrix composites, their toughness always decreased at the mean time, which limits their application in various fields. In order to meet the needs in the field of high technology and the ductility and toughness of composites, hybrid reinforcements with various types or different sizes were used in metal matrix composites. It combines the unique properties of the reinforcements to improve the properties of composites. The interactions between hybrid reinforcements make the metal matrix composites with lower thermal expansion coefficient, higher wear resistance and superior mechanical properties. In addition, it also reduced the cost of raw materials. Therefore, hybrid composites become the most potential material for application in aerospace and defense cutting-edge technology, and promote the progress of the entire industrial technology. This paper introduces types of hybrid reinforced metal matrix composites and progress in the research of hybrid composites. The basic structures of hybrid reinforcements and their advantages and disadvantages are summarized, and the future development of the configuration and function of hybrid reinforced metal matrix composites and key problems of engineering application are discussed.
